Abstract

PURPOSE: To make it possible to have the biprimary Z conversion characteristic, by making in-phase the sampling timing of the switched capacitor in case of input/ output, and also providing a capacitor in parallel with the switched capacitor of the input/output part.
CONSTITUTION: The timing by which the input voltage V1 is sampled by the input switched capacitor C1, and the timing by which the output voltage V2 is sampled by the output switched capacitor C2 are made in-phase. The transfer function H (Z) of input/output is shown by the following expression. H(Z)=V2/V1=(- C1'/Cf).1/(1-Z-1)-[(C1/Cf).[Z-1/(1-Z-1,]] Now, in case of selecting C1'=C1 then, H(Z)=-(C1/Cf).(1+Z-1)/(1-Z-1), and when it is compared with the transfer function of input/output of the analog integrator, the relation is expressed as S-Z conversion has been made. Namely, it becomes an integrator for realizing the biprimary Z conversion.
